T430 docking station question(s)

The power jack in the back of my T430 is out of commission. I bought a docking station and my T430 does run on it. I've never needed a ds because I use my T430 out in the field, at home I use desktops.

So, how fragile is the connection between notebook and docking station? Does it have a finite number of connections that be done before something breaks? I don't want to leave the notebook hooked to the docking station while carrying it around, surely it wasn't made for that.

So if I hook up/remove the notebook to the docking station say 3 times a day is that excessive?

 

First, power jack is not soldered on the motherboard. It is replaceable and not even that expensive.


3 dock/undocks every day is basically nothing. However in my experience that old dock connector itself isn't the greatest possible so there may be some unwanted half a second disconnects every now and then. I had T410 (horrible) and T420 (still bad), I replaced motherboard three times on the T410 and tried several docks. It would still sometimes blank my screens and disconnect usb devices if I touched the laptop while docked. When I found out that T420 was same as T410, I took an old Elitebook my client had sent for recycling and used it for couple years.

Docking connector type was changed in T440 and newer series, my current work laptop T450s works just fine.
